    摘要： The present invention provides a magnetic rotor bearing for suspending a rotor in a contact-free manner, in particular the rotor of an axial- or radial-centrifugal blood pump, comprising a permanent- and electromagnet arrangement which stabilizes the position of, and suspends the rotor in a stator, in particular a housing, and comprises a circuit arrangement connected to at least one position sensor or to the position sensor operating circuit thereof for the rotor. The rotor is suspended in the stator in a stable, contact-free manner by means of a permanent magnet arrangement except for a single geometric adjusting degree of freedom. The position of the rotor is stabilized only within the geometric adjusting degree of freedom not stabilized by the permanent magnet arrangement, by a permanent magnet arrangement located in the rotor and comprising at least one permanent magnet. The permanent magnet arrangement which co-operates with the electromagnet arrangement comprises at least one permanent magnet of the permanent magnet arrangement provided for suspending the rotor and consists in particular, of the permanent magnets of this permanent magnet arrangement positioned in the rotor. The circuit arrangement is a control circuit stabilizing the position of the rotor, during the absence of external forces, in a position of minimum energy requirement of the electromagnet arrangement.

    摘要： The present invention relates to a system for the central control of devices used during an operation, including a first control unit for control of the devices. The system is characterized in that a second control unit is provided which is connected to the first control unit for exchange of information. The first control unit may be embodied as closed system for control of at least those devices which carry out safety-related functions (safety-related devices), and the second control unit may be embodied as open system for control of the remaining devices which carry out non safety-related functions (non safety-related devices). The invention further relates to a method for the central control of devices.

    摘要： According to the invention, the use properties of a shock wave apparatus are improved by providing a metrological detection of the pressing force in addition to a sensual perception of the pressing force by a user. In this context, the invention relates to a shock wave apparatus having a housing and a contact device held at the housing, wherein the contact device is held via a force sensor at the housing in such a way that a force is transmitted from the contact device to the housing via the force sensor, at least partially.

    摘要： A high-frequency generator for high-frequency surgery is driven by a d.c. voltage supply. This d.c. voltage supply has a first working mode for transferring energy in a direction of the high-frequency generator, and also a second working mode for transferring energy in an opposite direction. With this arrangement, a particularly fast and efficient regulation of output voltage of the generator is possible. Therefore a reliable first cut may be performed on different kinds of tissue without any coagulation. Furthermore, owing to a high efficiency, a particularly small constructional size can be achieved.
